Typical Application Case
In a chemical plant’s storage tank area, multiple HART-enabled liquid level transmitters need to be monitored. Since the storage tank area is a hazardous location, intrinsic safety measures are required. The H6200A is installed in the control cabinet in the safe area, providing intrinsically safe power to HART liquid level transmitters in the hazardous area. It safely transmits 4-20mA liquid level signals and HART digital signals to the PLC control system. Through HART communication, the control system can read liquid level values, access transmitter diagnostic information, and perform remote configuration, ensuring safe and intelligent liquid level monitoring.
